e$)$ Two pressurized pipes A and $B$ are connected by a U$-$tube differential manometer as shown in Figure Q$2($e$)$ below. Pipe A contains a liquid with specific gravity $1\mathrm{.}6$ under a pressure of $110k\frac{N}{m^2}.$ Pipe B contains oil of specific gravity $0\mathrm{.}8$ under a pressure of $200k\frac{N}{m^2}.$ Taking the specific gravity of mercury as $13\mathrm{.}6,$ calculate the pressure difference between the pipes measured by mercury as a U$-$tube filing liquid.
